4 o1aims. (C1. cs i'fi') 4 This invention relates to mensuration devices and scales, and particularly to a door sizer and measuring device.

The main object of my invention is to provide means for taking the dimensions of a door opening wherein the door is to be hung in order to facilitate trimming the door to proper size and form in a single operation.

Another object is to provide a door sizer and measuring device which is built up of a plurality of adjustable sections including corner sections, side sections and top and bottom sections held together by a plurality of connecting members.

A further object is to have a door-measuring device of the character indicated in which the sections are slidably and adjustably interconnected and provided with additional outer stripsl for indicating the actual size to which they door is to be trimmed.

It is also an object to have such a door-measuring device provided with a plurality of small spacing members of predetermined size upon the.

outer strips making direct contact with the doorv posts, lintel and threshold, so that the stripswill l indicate the size of the door opening, while the strips indicate the size to which the door is to be trimmed. A practical object is, of course, to have a doormeasuring device as indicated which is light and simple in construction and easy to apply and adjust.

Other objects and advantages of the invention will appear in further detail as the specification proceeds. In order to facilitate ready comprehension of this invention for a proper appreciation of the salient features thereof, the invention is illustrated on the accompanying drawing formingv part hereof, and in which:

Figure 1 is a front elevation of the door sizer and measuring device made according to the invention and embodying the same in a practical form;

Figure 2 is an enlarged vertical fragmentary section taken on line 2-2 in Figure 1;

Figure 3 is an enlarged transverse fragmentary section taken on line 3-3 in Figure 1.

In the views the same reference numerals indicate the same or like parts.

When hanging doors, carpenters and trimmers usually find it necessary to trim and mark the.`

top, the sides and the bottom of the door in successive steps necessitating repeated placing ofthe door in position adjacent to the door posts until` nally the door is planed to proper size to iit.

in the doornopening. Suchtting is, of course,A

laborious, and especially if a large and heavy door is involved, itis true that a great deal of time. and labor is wasted merely in placing and marking the door and .removing yit for partial planing and trim-ming and repeatedly performing a similar maneuver with the door. The result is that the,` hanging of the door is a tedious and laborious,

and therefore expensive, operation which obvi-` ouslyshouldlnot be. I r I lUpon consideration this problem, it has occurred 4tofme that aaspecial measuringdevice.

ferring again to the drawing, in a door opening,y

generally indicated at 4, door posts 5 and 6 are capped by a lintel 'l and extend to the floor A8 which, for the present purpose, maybe a thresh-` old, in case there is such in a door opening, while uponl the inner sides of the door posts and at the. topare provided door stops 9 and ID. In order to1 take not'only the dimensions of the opening be .l tween door postsr and 6 and between lintel 'I and.

threshold 8, but also accurately the form ofthe opening', af door sizer or measuring device, generally indicated at II, is yplaced in position in the.

opening in such fashion as to rest against the: door stops '9 and I0, etc., when the device or frame;

is 'adjusted to fit the opening, as will now bedetailed.

The meausuring device Vprimarily includes a',

tubular cross consisting of upwardly and down-- wardly-extending tubes I2 and I3 and two intermediately-disposed and outwardly-directed tu bular arms I4 and AI5 Welded or brazed to verf, tical tubes I2 and I3 at the junction thereof to` form an integral unit. Into the outer ends of.

the side;r arms I4 and l5 extend a pair of connecting rods I6 and I1 slidably `adjustable in the` tubular arms and normallysecured in place by, a pair-of V i;humb'screws I8 and I9. In similar fashion into the upper and lower ends of tubes I2 and I3 extend ya pair of connecting rods 2U. and2'l slidably adjustable in these tubes, but normally held inf place by friction by means of:v

thetwothumb screws or wing screws 22 and 23V atthexends of -the mentioned tubes. The outerend of rod I6 extends into a tubular arm 24 which at its outer end is brazed or welded to the intermediate portion of a vertical tube 25 of equal length with the two tubes l2 and I3 a1- ready described, the inner end of tube 24 having a. wing screw Z6 by which to clamp the rod I6 in attained adjustment within the tube. At the upper and lower ends of the outer vertical tube 25 a pair of wing screws 21 and 28 serve to hold the upper and lower connecting rods 29 and 30 extending selected distances into tube 25. Tubes 24 and 25 constitute a T-shaped unit of which a counterpart is provided upon the other side oi the device in tubes 3| and 32 forming an opposite T-shaped unit in which rod ,l1y extends into horizontal tube 3l and is fixedr in attained position by means oi wing screw 33; while apair i further connecting roos 34 and 35 extend into the upper and lower ends of the vertical tube 32 and are secured in position by wing screws 36 and 31a f At the upper end of connecting rod A2li the latter extends into the lower endvof a depending' tube or pipe Se provided with a wing-screw 3B by which to nx rod 2u in attained position, while at the upper end the tube 38 is brazed to the intermediate portion of horizontal upper tube 4c formingr a T therewith, and in similar fashion the lower end of connecting rod 2| extends into the upper end of a vertical tube 4|' in which it may be secured in selected position by means of wing or thumb screw 42, tube 4| being brazed or welded at the lower end thereof to a horizontal tube 43 forming with tube 4| an inverted T. At the ends oi the upper horizontal tube 40 the latter is provided with wing screws 44 and d5 for adjustably securing the connecting rods it and 4| in extending'position from the ends of tube 4E), while in similar fashion the bottom tube 43 has two end wing screws 48 and 49 for securing a pair of lower connecting rods 5|] and 5| adjustably extending from the ends of said tube 43.

The corners now remain to be considered upon the device, and thus at the upper left corner a horizontal tube 52 extends in upon connecting rod 40 and is adjustably secured thereon by thumb screw 53, the other end of tube 52 being brazed or welded at a right angle to the upper end of a vertical tube 54 which at the lower end extends down upon the previously-mentioned vertical connecting r'od 29 and is adjustably sea cured thereon by wing screw 55. In the upper right corner, the horizontal tube 56,l which is permanently secured to the vertical tube 51, extends in upon connecting rod 41 and is secured thereon by wing screw 58, while the lower end of the vertical tube 51 extends down upon the connecting rod 34 and is adjustably secured thereon by the wing screw 59.

a manner corresponding to the corner members just described with reference to the upper corners of the door opening, the lower corners are similarly provided, as :for example, at the lower left corner is the vertical tube 60 permanently fixed tc the lower horizontal tube 6|, and extending up on connecting rod 30 and beadju'stably secured thereon by wing screw 62, while the lower horizontal tube 6| extends in connecting rod 50 and is secured adjustably thereto by wing screw 53. In similar fashion the vertical tube 64 at the lower right extends up on connecting rod 35 and is adjustably secured thereon by wing screw 65 and at the lower end tube 64 is permanently secured to the lower horllow and high doors ranging from a width oi approximately 231/2 inches in width and 6 feet or less in height to about 36 /2 inches in width and '1 feet and 1/2 inch in height, these dimensions being, however, arbitrary and capable of varia-tion.v

Upon the vertical tubes 25 and 32 are brazed or weldedv three equdistantly-spaced nipples 58, te and l'. In similar fashion tube 32 is provided with outwardly-'projecting nipples 1|, 112 and 13, and the upper and lower tubes d and 43 are likewise provided with such nipples 1d, 15, 16 and il", and the vertical corner tubes ell and 51 are also provided with the nipples it, 19, 8u and 8|-, and the lower vertical corner tubes et and 64 are likewise provided with such nipples at 82, 83, 84 and 85. The upper horizontal corner tubes 52 :and 56 have nipples 8e and el, as well as 38 and 89 secured thereto, and finally the lower horizontal tubes 6| and 6G are similarly provided with downwardlyeprojected nipples di?, 9|, 92 and 93. The purpose oi' the nipples will now be explained, it being noted that the central cross, as well as tubes 24, 8|, 58 and di, are not thus provided.

As best seen in Figures 2 and 3, the rigidlyixedv nipples 14 and 69 are provided with thumb or wing screws 94 and 95, the nipple 69 illustrating the presence of a short st'ud projecting into the outer end of the nipple and xed in place by wing screw e5, while a measuring strip of metal 9T is Isecured to the outer end of stud d by means of a screw S8 having' a head e@ exteriorly of the strip which may vary from 5"-2 to 1A; of an inch in. height, the latter dimension being preferred. The upper strip |05, seen in Figure 2, is held by the head |0| of a screw, not shown, within nipple 14 also receiving a stud in which the screw is secured. All of the nipples upon the entire device are similarly constructed as described in connection with Figure 3, and strip |05 is provided not only with screw head iti, but also |62, and similarly nipples 86 and 8'.' are provided with measuring strip |03 held by screw heads |64 and |05 and nipples 88 and 85 having the strip i held by screw heads |01 and |03 in line with strips |0o and H33. At the bottom, nipples 16 and 'l1 are provided with the measuring strip |09 held by screw heads ||0 and I||, while the nipples 90 and 9| have the measuring strip H2 held by screw heads ||3 and H4, and nipples 92 and 93 are provided with the strip H5 held in line with strips |09 and ||2 by screw heads lit and The intermediate vertical strip 91 at the left is held not only by the screw head 89, but also by screw heads H8 and lig exteriorly of nipples B8 and 10, while on the opposite side measuring strip |20 is held upon nipples 1|, 12 and 13 by screw heads |2l, |22 and |23. A1; the upper left, the two nipples 'I8 and |9 are provided with a, measuring strip |24 held by screw heads |25 and |28, and on the opposite side, nipples 80 and 8| are provided with the measuring strip |21 held by screw heads |28 and |29. At the lower left, nipples 82 and 83o'ntubei60'are provided with a vertical measuringstrip |30,held,by screw heads |3|' and |32, and at" the loweruright, `nipples 84 and 85 ontube 04 are provided with the measuring strip' |33 held byv screw heads y| 34 and |35.

The arrangement is such that when a device isiplaced f in position in the door; opening: 4, a suicient `number ofthe wingscrews uponv the various tubes are `loosened order to allowthe connecting rods to slide until the screw heads upon the outer sides of the various measuring strips strike the door posts 5 and 6, the lintel and the threshold or floor 8, when the screws are tightened so that all of the screw heads on the measuring strips are held in actual contact with the various parts of the door opening mentioned.

Due to the large number of wing screws involved, as well as the various tube elements, it is possible to obtain a faithful measurement of all portions of the door opening including the corners, the top and bottom, and the sides, and when all of the thumb screws are tightened, the entire measuring device is carefully slid out of the door opening and then laid upon the door which is then scribed along the various measuring strips, as for example, 97, |24 and |30 upon the left, |20, |21 and |33 upon the right, |09, ||2 and ||5 at the bottom, and |03, |00 and |06 at the top, ignoring all of the screw heads and the scribing being performed upon the outer sides of the strips. The thickness of the screw heads provides just the proper amount of clearance between the door and the door posts, as well as the lintel and the floor or threshold, so that it will be possible to open and close the door smoothly without contact thereof against any portion of the door opening. When the door has been thus scribed about the two side edges and top and bottom edges, it is a simple matter to plane these edges to the scribed lines and the hinges then l are brought virtually together so that the connecting rods are concealed within as then all of the tubes meet and wholly enclose the mentioned connecting rods.

From the foregoing, it is evident that it will be possible to take the dimensions of any door opening, whether it be perfectly rectangular or not, and the measurements obtained may thus be directly transferred to the door that is to be hung.

Manifestly, variations may be'resorted to and parts and features may be modified or used without others within the scope of the appended claims.
